Nor did your original question define the spot to be hit all too

'Flat binary' and 'linked ... later' are a contradiction to each
other. Flat binary means that no 'control information' is in the file,
just raw executable code and data. Stuff like addresses that the
linker will have to fix up for relocating the code to its final
position would be missing, i.e. you cannot possibly 'link' this to
anything else, later.

DJGPP tools can generate flat binary, in principle. See 'objcopy
--help' and 'objdump -i' output for some details, and/or read the full
binutils documentation in 'info'.

You should re-think your strategy, and ask more clearly *what* you
want, and why. Your question has been rather vague, so far.
